The pregnancy subplot involving Carrie-Anne Moss' character Helen Robinson was only added because Moss was really pregnant during filming, and they added the pregnancy scenes to keep the continuity through the movie as she grew larger.

Director Andrew Currie stated his thoughts about Carrie-Anne Moss as follows: "She's just so well-prepared and at the same time intuitive. What she brought to the role was such a sense of grace, timing, and beauty. Well, she brought just the right balance to the movie in all areas."
